211RA c 2005Ku31: {+215}Th recoils from the {+170}Er({+50}Ti,5n) reaction
211RA2c were separated from the beam using a velocity filter SHIP at GSI and
211RA3c implanted into a position-sensitive 16-strip PIPS semiconductor
211RA4c detector. Measured (recoil)-|g-|a-|g coincidences-correlations and
211RA5c |g-rays. Ge-Clover detector was used for |g measurements. Measured
211RA6c E|a, E|g, I|g.
211RA c 2000He17: {+215}Th recoils from the {+170}Er({+51}V,p5n) reaction
211RA2c were separated from the beam using a velocity filter and implanted
211RA3c into a position-sensitive semiconductor detector. Measured E|a, E|g,
211RA4c |a-|g coin. Detector: Ge for |g rays.
211RA c 1973Mi03: {+215}Th recoils from the {+182}W({+35}Cl,pn) reaction were
211RA2c separated with the JAERI recoil separator and implanted into a PSSD.
211RA3c Measured E|a, T{-1/2}.
211RA c 1968Va18: Activity produced by {+206}Pb({+16}O,7n). Measured E|a,
211RA2c I|a. Semiconductor detector.
